It's modest compared to the more than $300,000 that SEIU gave to Kroger's campaign. That had a lot to do with payback aimed at Kroger's opponent, then-state Rep. Greg Macpherson, who had authored a public employees pension bill the union didn't like.

This time, the unions don't have such a big stake in the attorney general's race. But there are signs that Holton is making some of the same inroads with the unions that Kroger did.

Holton's Democratic primary rival Ellen Rosenblum, a former judge, lists the endorsement of Oregon AFSCME. Holton has reported raising about $222,000 (not including those two new union contributions) while Rosenblum has raised nearly $200,000.

Since no Republican is running in the race, the attorney general's race will essentially be settled in the primary.
